September 30: Sulfuric acid is detected on Europa's surface. — Dr. Kenneth Nealson, head of JPL's astrobiology unit, said, "Although sulfur may seem like a harsh chemical, its presence on Europa doesn't in any way rule out the possibility of life. In fact, to make energy, which is essential to life, you need fuel and something with which to burn it. Sulfur and sulfuric acid are known oxidants, or energy sources, for living things on Earth."

September 26: Experimental Evolution with Microbes and Molecules — Experiments that follow the evolution of bacteria were the subject of a special colloquium held during the 99th American Society for Microbiology General Meeting in Chicago, May 30 - June 9. Following pedigreed strains of bacteria for thousands of generations, these experiments measure their fitness and analyze their genetic makeup along the way. Such experiments are getting ever more attention, and deservedly so. The bacteria adapt to changed environments and undergo genetic mutation as predicted by darwinism. They are widely seen as directly supporting the theory.
The experiments are not without surprises. When the bacteria are examined on a fine scale (every 100 generations), stepwise evolution is observed; only at a larger scale (every 500 generations) does the evolution appear smooth. Also, some lines undergo mutation three times as fast as others "with very little change in the cells' performance versus other lines." And lines that mutate especially fast, "hypermutators," do poorly.
Most interestingly, the experiments show, "After the initial burst of adaptations, the rate of change among the bacteria slows. After 10,000 generations in this constantly maintained growth medium, analysis indicates a 50% total increase in fitness; after 20,000 generations, the improvement over the ancestors is measured at 60%." This result could indicate that the bacteria approach a maximum fitness beyond which they cannot evolve in the closed experiments.
Moreover, the experiments have yet to report any evolutionary progress of the sort that would be needed for life to evolve from bacteria to humans. The observed adaptations tend to consist only of changed diets and the like. These adaptations are made possible by the enabling or disabling genes already contained in the bacterial genomes. Darwinism would interpret this lack to mean that the experiments need to run longer. But it may indicate that the darwinian mechanism by itself cannot produce sustained evolutionary progress. We will continue to watch for news from these experiments.
Evolutionary progress requires new genetic programs. New genes can be installed by lateral gene transfer (LGT), as we already know. Cosmic Ancestry holds that LGT is an essential mechanism behind evolutionary progress. If so, the fact that these experiments are closed to the input of new genes would account for their lack of evolutionary progress.

September 16: The strange curves on Europa — A team from University of Arizona, Tucson, has a reasonable account of the cycloidal lines stretching hundreds of miles across the southern polar region of Europa. They believe the bulge of a 100-foot tide cracks the ice in long curves as stress vectors rotate during the Europan day (about 3.5 Earth days.) New segments 40-120 miles long would form when the cycle repeats on successive days, making a chain of broken curves. The team estimates that the ocean on Europa is about 100 miles deep.

September 7: Liquid water in another meteorite —
NASA scientists have apparently found liquid water in another rock from space, suggesting that it may be common in meteorites, according to Michael Zolensky of the Johnson Space Center in Houston. This example was found in the "Zag meteorite," a 300-pound rock that broke into pieces when it struck a remote area of Morocco in August, 1998. The water in it was first reported at a conference in South Africa, in August, 1999.
It was also Zolensky's team that announced, less than two weeks ago, liquid water in the Mohanas meteorite. Examining the meteorites promptly is critical, NASA says, because the salt crystals containing the tiny water pockets could be dissolved by a single rain. Thanks again, Keith Cowing, for the alert.

September 2: Viruses have been found deep under the Greenland icepack. Biologists from Syracuse University and SUNY, Syracuse, found a common virus that infects plants in ice laid down from 500 to 140,000 years ago. The virus particles were carried there by air currents. Indeed, members of the research team have previously found whole particles of the same virus in clouds. The tomato mosaic tobamovirus was found when PCR tests looking specifically for it were positive. The researchers believe that tests for other common viruses would also be positive, and that viruses stored in the ice for centuries retain the capability to infect their usual hosts. Thanks, Keith Cowing, for bringing this story in New Scientist to our attention.

August 27: Liquid Water Found in a Meteorite — A meteorite that fell in Monahans, Texas, contains liquid water, according to Michael Zolensky's team at NASA's Johnson Space Center. The water was sealed in tiny cavities in salt crystals, some of which also held tiny bubbles of vapor. The water is believed to have been sealed there since before Earth was formed.
V= Vapor, L= Liquid
scale bar= 5 micrometers
Seven boys playing basketball had seen the meteorite as it fell, on 22 March, 1998. They picked it up while it was still warm and astutely called the police. NASA was examining it within 48 hours. That promptness and NASA's methods make the finding more credible than any similar previous claim — and there are some.
"Monahans" is an ordinary chondrite, a kind of meteorite previously thought to be dry. However, carbonaceous chondrites, perhaps remnants of icy comets, were already believed to have once contained flowing water. Now the formation of a carbonaceous chondrite, Allende, is also under review. A report by planetary scientist Adrian Brearley of the University of New Mexico suggests that Allende came from an asteroid that got wet after it was formed.
Life in space can be preserved and remain viable in a completely dry environment, but cells require liquid water for any metabolism or replication. Now we have even stronger evidence that it's available.

August 24: DNA protection by biocrystallization may be crucial and widespread in prokaryotes. A team from The Weizmann Institute and Harvard found that starvation and other stresses induce E. coli to produce a protein that quickly co-crystallizes with DNA, protecting it from damage. Crystallization might preserve DNA even after the original cell dies, we suspect. Thanks, Ken Jopp, for noticing this story.

The history of science offers example after example of apparently inexplicable features for which perfectly rational explanations were found. In nearly all such cases, assumptions that were universally believed obscured the truth so effectively that progress toward a solution seemed impossible — Thomas Gold
August 23: The Deep Hot Biosphere is full of challenging new ideas that are well supported and plainly expressed, from "The Deep-Earth Gas Theory" to the end. Author Thomas Gold, a recognized expert in several fields, begins with geology. When he worked in the petroleum industry, he became convinced that petroleum could be found far deeper underground than it could if it is made from earthly vegetation, as the consensus theory holds. His evidence for deep petroleum is compelling and easy to follow. So, Gold believes oil and gas are "primordial," by which he means "older than the planet". But evidence that petroleum is biologically produced is also compelling. For example, petroleum contains amino acids that are predominantly left-handed, as in life. To resolve this "petroleum paradox," Gold proposes that there is microbial life thriving on the oil and gas in the pore spaces miles underground. Gold makes a good case for this deep life, and now many others are agreeing with him.
One universal assumption that Gold does not question is that "primordial" necessarily means "abiogenic." If those terms were disentangled, another resolution to the petroleum paradox would be possible — methane could be older than the planet but still biologically produced!
Gold also presents fascinating new ideas about diamonds, the formation of metal deposits, earthquakes, and glaciers (instead of rivers) on Mars. Finally, he proposes that the origin of life would be more likely to occur deep underground than on the surface of a planet. Even here Gold is persuasive. Of course, he does not explain how life's encoded instructions could have come into being — a missing element in all scientific accounts of the origin of life. That life must have an origin in the finite past is an assumption that almost no one questions.
Although our assumptions are different from Gold's in key respects, we liked the book quite a lot. Gold's plain, precise writing made it both edifying and fun to read. The Foreword by Freeman Dyson was good, too.

August 12: New computer model of evolution — Richard Lenski of Michigan State University and others have conducted a computer simulation of evolution that uses simple replicating organisms and complex programs that enhance their replication by issuing "metabolic rewards." Lenski, a biologist, has previously experimented with thousands of successive generations of evolving bacteria, and team members Charles Ofria and Christoph Adami are principal developers of the artificial life program, Avida. This collaborative experiment is just what we have asked for to demonstrate whether darwinian evolution in a closed system can produce the lengthy new genetic programs necessary for sustained evolutionary progress, in real or artificial life. No such progress has yet been claimed for this experiment. Rather, the group has focussed on the effects of "interactions of mutations." We will watch closely for future developments.
